Constructors¶

new

  my $sender = Email::Send->new({
      mailer      => 'NNTP',
      mailer_args => [ Host => 'nntp.example.com' ],
  });
    

Create a new mailer object. This method can take parameters for any of the data properties of this module. Those data properties, which have their own accessors, are listed under "Properties".

Properties¶

mailer

The mailing system you'd like to use for sending messages with this object. This is not defined by default. If you don't specify a mailer, all available plugins will be tried when the "send" method is called until one succeeds.

mailer_args

Arguments passed into the mailing system you're using.

message_modifier

If defined, this callback is invoked every time the "send" method is called on an object. The mailer object will be passed as the first argument. Second, the actual "Email::Simple" object for a message will be passed. Finally, any additional arguments passed to "send" will be passed to this method in the order they were received.

This is useful if you are sending in bulk.

METHODS¶

send

  my $result = $sender->send($message, @modifier_args);
    

Send a message using the predetermined mailer and mailer arguments. If you have defined a "message_modifier" it will be called prior to sending.

The first argument you pass to send is an email message. It must be in some format that "Email::Abstract" can understand. If you don't have "Email::Abstract" installed then sending as plain text or an "Email::Simple" object will do.

Any remaining arguments will be passed directly into your defined "message_modifier".

all_mailers

  my @available = $sender->all_mailers;
    

Returns a list of available mailers. These are mailers that are installed on your computer and register themselves as available.

mailer_available

  # is SMTP over SSL avaialble?
  $sender->mailer('SMTP')
    if $sender->mailer_available('SMTP', ssl => 1);
    

Given the name of a mailer, such as "SMTP", determine if it is available. Any additional arguments passed to this method are passed directly to the "is_available" method of the mailer being queried.

Writing Mailers¶

  package Email::Send::Example;
  sub is_available {
      eval { use Net::Example }
  }
  sub send {
      my ($class, $message, @args) = @_;
      use Net::Example;
      Net::Example->do_it($message) or return;
  }
  1;

Writing new mailers is very simple. If you want to use a short name when calling "send", name your mailer under the "Email::Send" namespace. If you don't, the full name will have to be used. A mailer only needs to implement a single function, "send". It will be called from "Email::Send" exactly like this.

  Your::Sending::Package->send($message, @args);

$message is an Email::Simple object, @args are the extra arguments passed into "Email::Send::send".

Here's an example of a mailer that sends email to a URL.

  package Email::Send::HTTP::Post;
  use strict;
  use vars qw[$AGENT $URL $FIELD];
  use Return::Value;
  sub is_available {
      eval { use LWP::UserAgent }
  }
  sub send {
      my ($class, $message, @args);
      require LWP::UserAgent;
      if ( @args ) {
          my ($URL, $FIELD) = @args;
          $AGENT = LWP::UserAgent->new;
      }
      return failure "Can't send to URL if no URL and field are named"
          unless $URL && $FIELD;
      $AGENT->post($URL => { $FIELD => $message->as_string });
      return success;
  }
  1;

This example will keep a UserAgent singleton unless new arguments are passed to "send". It is used by calling "Email::Send::send".

  my $sender = Email::Send->new({ mailer => 'HTTP::Post' });
  $sender->mailer_args([ 'http://example.com/incoming', 'message' ]);
  $sender->send($message);
  $sender->send($message2); # uses saved $URL and $FIELD
